In the course of Octavian’s Illyrian war (35–33 BC), the navy played an important role, both at sea and on the rivers. Some of its actions are documented by ancient historians (notably Appian and Cassius Dio), while others are hypothesized on the basis of reconstructed military strategy and the logistics of the war. The geographical repartition of the defeated peoples suggests that they were attacked at different times and from several directions: from Aquileia (the Carni and Taurisci), probably from Ravenna (the northern Liburnian islands and mainland). One of the supply bases for the Roman army operating in the north was Senia, while the pirates in the southern Adriatic must have been attacked from Brundisium. Cassius Dio even mentioned naval battles against the Pannonians at Segesta/Siscia, in one of which Menodorus, the naval commander of Sextus Pompeius, lost his life.
